To all whom it may concern:

Be it known that .I, FRANK L. RIDDLE, a

citizen of the United States, residing at Los Angeles, in thecountyofLos Angeles and State of California, have invented'a new and useful Infant's Portable High-Chair Seat, of which the following is' a specification.

. This invention relates 'to a seat which is adapted to be attached to the back of an ordinary chair to furnish a seat higher than the regular seat of the chair for the use of infants, and has for its ob'ect to produce a device of this character which may be readily detached, when desired, and folded up into a very small compass.

A further object is to rovide suitable stra s for preventing the in ant from falling or s ping off from the seat and to provide for aX usting the height of the seat.

. mg the Referring to the drawings :Figure 1 is a perspective view of an ordinary chair, showortable seat attached thereto and extende ready for use. Fig. 2 is a perspective view of the seat when detached and the seat as provided with lugs ofthe form shown in Fig. 3.

The seat comprises two sections 1 and 2 which are hinged together, each section comprising a U-shaped tube or rod 3 having knuckles 4 which are pivoted together by a pintle 5. Thishinged construction may consist of any of the well known forms of binge devices. A seat '6, preferably of canvas, is secured to the two sections 3 and at each e the seat 6 is cut away, as at 7, to leave sufhcient space for the hinge. The edges of the canvas 6 are referably sewn around the rods or tubes and are hemmed, so that there are no raw edges of the seat which could ravel. Supporting straps 8 are attached at each corner of the front section land are folded at the top to form a loop 9, the length of which is regulated by a shp buckle 10, the loop engaging a cross bar 11 of a hook 12. Each hook 12 i also has a lower bar 13 which is engaged by a loop 14 of a rear strap 15,: each rear strap 15 beingsecured to the rear section 2. The loops 14 are regulated by similar slip buckles 10.

at the cut-away portion 7 of straps 8 and 15 may be regulated to adjust adapted to .be clas ed over the u per edge of an'ordinary chair ack, as clear y indicated in Fig. 1, and thus support the infants seat at the desired height. In order to hold the infant in place a strap 16 is attached to the rear section 2 and is provided with a buckle '17. A strap 18 is attached to one of the fastener 19 to the other strap 8 to hold the straps 8 in position. The strap 18 is detachable at one end to permit the infant to be readily placed on the'seat or removed therefrom. a

The seat may readily be detached from the chair .and the two members 1 and 2 folded together, as shown in Fig. 2, and then the straps 8 and 15 may be folded around the carried or stowed away.

Where theseat is to be used with a s eeially constructed chair, as indicatedm 1g. 3, the rear section will be rovided with two slotted lugs 20 each of w 'chis adapted to detachably engage a pin 21 on the rear chair post 22, while the front section 1 may have two lugs 23, each of which is perforated and adapted to be secured to the front 0st 24 by a thumb screw 25, as shown. us by of the seat may be released and then the rear edge may be removed by slightly lifting it and then withdrawing it. A tray 26 may rear posts'22, and snapl hooks 29 serve to support the tray from t e straps 8, preventing the tray from being displaced by the 111 'fant.

A step or foot rest30 may be provided with arms 31 ivoted to the front ostsv 24 perm use.

The rear legs 22 are connected by braces 32, and the front le s24 are connected'by similar braces 32. lhe front legs 24 are connected with the rear legs 22 by braces 33 which have pivotal connections at 34 wh ch enable the front legs to be swung up and he close a ainst the rear legsafter the seat has been either tilted back against the back of the chair orremoved therefrom.
